| 摘 要： | 针对新型纳米碘化银催化剂在人工影响天气中有较大的应用前景,采用粉末化学液相沉淀法在常温常压条件下制备了与冰晶具有相近结构的纳米碘化银(AgI)粉末,采用场发射透射电子显微镜和X射线衍射谱等对碘化银粒子的结构特性、尺寸分布和比表面积等进行了与成冰性能相关的实验表征.与目前用的常规碘化银进行了表征特征对比表明,该纳米碘化银粒子的晶格常数更接近于冰,尺寸在30～90 nm之间,具有较高的吸附能力和比表面积. |

| Abstract: | The application of new nano-silver iodide (AgI) catalyst to weather modification was studied. Nano-silver iodide powder with closed ice crystal structure was prepared by using a powder precipitation method at normal temperature and pressure. The size distribution and structural property of the nano-silver iodide were characterized by using field emission transmission electron microscopy and X-ray diffraction spectrum. These characterization results showed that the lattice constant of the nano-silver iodide is closer to the ice than the conventional AgI, the nano-silver iodide has a grain size range of 30-90 nm, higher adsorption capacity and larger specific surface area than the conventional silver iodide. |
